To all whom it may concern Be it known that ll, JOHN J. SMITH, of lBrookline, in the county of Norfolk and State of Massachusetts, have invented a new and useful Process of Treating Sewage, Garbage, and the like, of which the following is a specification.

The object of my invention is to provide a simple and efficient process of treating sewage, garbage or the like not only to retain those parts of said material which have but also to render the treatment harmless so far as giving 0 deleterious gases is concerned.

My invention is based in part on my discovery that a deodorizing solid preferably in powder form, may be used to withdraw the gases of said material absorbing and neutralizing them.

A feature of my invention consists in applying heat in the neighborhood of the material to make the air take up moisture and then removing the moisture by condensation.

In the drawing the figure is a sectional elevation of a machine for my system.

The sewage or garbage is admitted to re- A. and from there passes through opening a controlled by gate valve a; As the material passes through said opening it falls upon carrier B made of wire or other- Wise perforated to allowyfor drainage. portion of the water in drain through the carrier B and carrier and into chamber D and the rest of the material will be dropped upon the larger carrier B which is perforated and as it advances water will be drained through the perforations of this carrier and fall into chambers D, D and D The material will be advanced by carrier B and then after it passes Wall E a finely powdered mixture of ground bone charcoal and powdered peat loam soil will be applied from bin 13"., the feeding of the mixture being controlled by corrugated roller B which is operated by a belt running to shaft 1) which operates car- Shaft b is connected by a belt with shaft 5 which may be operated in any suitable manner, there being also a belt to operate brush 6 for the purpose of cleaning the carrier B as it moves. Shaft b operates carrier E upon which carrier the material falls after leaving carrier B and rier E at one end.

carrier E conveys the material to a suitable outlet at E. A heating device in the form of steam coils F is provided and condensing coils G operated by a suitable ammonia or other cooling plant a J represents a suitable blower for blowing on to the material a finely powdered deodorizing compound such, for example, as charcoal or earth or both as it is advanced by carrier B in order that it may absorb and neutralize disagreeable gases in the material and thus prevent their arising from the moving mass. A brush cleaner B is used to glelan carrier l3 and is operated by a suitable 'llhe filter at the bottom of chamber D consists of a base of coarse gravel upon which are placed a plurality of tiles F the spaces between the tiles being filled with any suitable filler, preferably cement.

in using my system the material will be partially drained by member 13 and partially by B the water dropping into chamber D, passing through the filters F and thence from beneath'chamber D into chamber D and is then filtered through the filters F which are like those of chamber D and form the floor of chamber D, waterproof and the clear water falling into chamber D elsewhere through outlet D, the water in D being available in case outlet D is not used. for use in the condensing coils through pipe f or for other uses. The blower applies deodorizing compound to absorb and neutralize the gases and prevent the waste of valuable fertilizing matter and to prevent the escape of harmful gases which might be injurious to attendants or to others. Before reaching the steam coils, and preferably just before reaching them, deodorizing compound is applied to quiet the gases by absorbing and neutralizing them so that they will not be driven 0d when the material comes into adjacency with the steam. coils, the heat of which makes the air in the neighborhood of the material to be dried more readily take up what moisture remains in the material and renders that moisture in condensed when the material advances on carrier E into adjacency to the condensing coils at which time the moisture will be condensed on the condensing coils because of and thence out to the ocean or,

condition to bewall D being I age, garbage or'the like consisting the coldness of the latter and the material free from moisture will pass to outlet E in readiness for use as a fertilizer.

My system is very simple but at the same time very highly efiicient as it preserves a veryhighpercentage of the material available for fertilizing purposes and at the same time is not in anyway harmful to attendants or a nuisance to the neighborhood.

In its broadest aspect my invention covers the use of a deodorizing solid preferably in powder form and this deodorizer may be charcoal or earth or both, my discovery be ing that the gases will be fully absorbed and neutralized by the application to the material of such deodorizing material. I do not claim the above described apparatus in this application as I intend to make it the subject of another application.

at I claim is:

1. The method of treating drained sewage, garbage or the like consisting .in applying deodorizer to the material, then heating the material to make -the air in the neighborhood of the material to be dried more readily take up the moisture and then removing the moisture by condensation.

2. The method of treating drained sewage, garbage or the like consisting in applying to the material a deodorizer consisting of charcoal and earth, then heating the material to make the air in the neighborhood of the material to be dried more readily take up the moisture and then removing the moisture by condensation.

3. The method of treating solids of seW-' age, garbage or the like consisting in applying a deodorizing powder to the material and allowing it to absorb the gases of said material.

4:- llhe method of treating solids of sewin applying deodorizer to the material, then heating the material to make the air in the neighborhood of the material to be dried more readily take up the moisture and then removing the moisture by condensation.

5. The method of treating solids of sewage, garbage or the like consisting in applying deodorizing material to quiet the gases by absorbing and neutralizing them, then heating to such an extent as to make the air in the neighborhood of the material to be dried more readily take up the moisture but not sufficiently to volatilize said gases and then removing the moisture by condensation.

6. The method of treating solids of sewage, garbage or the like consisting in applying charcoal and peat loam soil to quiet the gases by absorbing and neutralizing them, then heating to such an extent as to make the air in the neighborhood of the material to be dried more readily take up the moisture but not sufficiently to volatilize said gases and then removing the moisture by condensation.

7. The method of treating sewage, garbags or the like containing liquid and solid material consisting in separating the liquid from the-solid, then applying deodorizing material to quiet the gases by absorbing and neutralizing them, then heating to such an extent as to make the air in the neighborhood of the material to be dried more readily take up the moisture but not sufliciently to volatilize said gases and then removing the moisture by condensation.

8. The method of treating drained sewage, garbage or the like consisting in heating the material to make the air in the neighborhood of the material to be dried more readily take up the moisture and then removing the moisture by condensation.

9. The method of treating drained sewage, garbage or the like consisting in heating thematerial to such an extent as to make the air in the neighborhood of the material to be dried more readily take up the moisture, but not sufficiently to volatilize the gases, and then removing the moisture by condensation.
